It seems like only yesterday that The Waffle Bus and Bare Bowls were our latest mobile food obsessions — not that we'll ever get tired of vegetarian stews or strawberry Irish cream creme brulee waffle sandwiches. (One is for when we are being good. One is for when we are so, so not.)

But the food truck movement shows no signs of, um, slowing down and whether it's siopao or French food, there's always something new to try.

Here's what's on our radar and hitting the streets soon:

L'es-Car-Go

While some food truck owners, (like The Eatsie Boys and Green Seed Vegan) are expanding into brick and mortar shops, there are also restaurants who are adding mobile units. L'es-Car-Go is a forthcoming food truck from Bistro Provence owners Jean-Philippe and Genevieve Guy, the first French food-based truck in Houston.

The truck is scheduled to launch sometime this month, and will cater to West Houston office parks and events with a menu of fresh French soups, hot sandwiches including a Cordon Bleu and a Croque Monsieur, and an array of snail specialties, as befits the name.

There's no paucity of burgers on the streets of Houston, but Donramon and Michael Jante are mixing up the formula at Flip N' Patties with Filipino flavors (and slang in the burger names) and a menu of Filipino street foods including siopaos, chicken pupu, pork adobo and much more. Look for them starting in May or June around the Montrose/Midtown/Heights neighborhoods.

Mexican foods on wheels doesn't have to be all about tacos. Hitting the streets this month, Sirena promises "seafood cocktails and regular ol' delishusness from the Mexican coasts," and is already tantalizing Facebook and Twitter fans with her tempting photos of campechana, empanadas, ceviche and aguachile.

Hungry yet?
